Question

What two numbers multiply to equal 50 and add up to equal -15

Answer 1

The two numbers are 5,10. Which is multiply to equal 50 and add up to equal 15.

Step-by-step explanation:

Step:1

      Let, X,Y.

      Where X, Y are two numbers.

Step:2

      Form the Multiplication equation from given,

     X×Y=50         (∵ Multiply to equal 50)

Step:3

      Form Addition equation from given,

      X+Y= 15        (∵ Add equal to 15)

Step:4

      Check for alternatives to satisfy both equations

     Assume, X=1, Y=14

     1+14=15 (Satisfy addition equation)

     1×14=14 (Not satisfy multiplication equation)

     Assume, X=2, Y=13

     2+13=15  (Satisfy addition equation)

     2×13=26 (Not satisfy multiplication equation)

similarly.,

    assume X=5, Y=10

    5+10=15   (Satisfy addition equation)    

    5×10=50  (Satisfy multiplication equation)

So, the two numbers are 5,10.
